Speed stat incorporation

If Niantic decide to incorporate the speed stat what do you think it would control?
I always thought it would be cool for a really fast Pokemon like jolteon to attack really quick, whilst a slow Pokemon like snorlax or blissey would attack horrendously slowly. They could also do something with dodge times, but this could mean alakazam would be a speedy attacker. Confusion would be faster. And still do insane damage. The problem being that there are so many counters. A scizor or Tyranitar or houndoom can tank up those hits and hit back stronger. Thus why this system could actually work. Pokemon like electrode who have no purpose in the meta could suddenly gain one.
